I have "front" surface aluminum laser mirrors with SiO2 coatings right now ;-))

The blue is the protective shipping film.  Tricky to get off !  Now I 
have to try not to finger or scratch them!!

As far as I know, my old camera will do fine.  I might add another 
big front surface mirror to give a better view angle. A "Rev.2" 
thing.  The wooden body is cheap and simple to change at will 
:-)))  If I run into a problem, we'll use your camera ;-))  I am 
concerned that I put the lexan shield at 90 degrees to the camera 
lens so it might reflect badly...  But I'll give it all a try and 
probably chop out a whole new rev2 frame once the bugs are all found out.

The "spark" is a one time thing so I don't think it can be "stacked" really.

I'll try to get something tomorrow.  Have to go to a big funeral 
Tuesday...  I need to mount the calibrator light source in there too 
still...  I did mange to clean up the labs though :o))  It is coming 
together well now ;-)))

Cheers,

        Terry
